I'll comment on the new stuff, everything is still as great as I remember it from two months ago, so I won't repeat that:
The DEEP LORE book intro is new (I think), I liked that. With the full name Aozora reveal (which hints towards the Mr. Sol = Ao's father theory, which is commonly accepted as true in the Soporo fandom (Soporodom for short)).
The new final boss UI is cool, especially with the draining shield/life bar, it really gives a better feel for how long the fight is (although I feel it is shorter now than before, or maybe my Soporo skills have just increased that much). No wait, I figured it out, it's the new Ao controls, it just feels better to control now. Good job on that!
Human form is cute too, I'm looking forward to what it can do, maybe human things like working a day job or make indie games or something.
And of course my favorite addition, the chat (fr.: cat) log, which makes it possible to read the story without destroying the S-rank run. Very clever solution for that, putting it in the pause menu!
Still super fun, looking forward to the shop keeper and/or world 2!
